Title: Laser-diode for surgical use - is focussed to uniform image by two orthogonal compensating cylindrical lenses
Inventor: MIZUNO KATSUYASU
IPC: G02B6/42
Filed: 1991-04-11
Abstract: A laser-diode (1) emitting at 800 nm from a narrow PN junction is focussed through a lens-system which compensates for the difference in beam-divergence between its principal planes.  Emission in the plane of the junction (Fig.5B) is brought to the image (8) through a convexo-cylindrical lens (6) but transversely, as a point-source (Fig. 5A) it is partially defocussed by a concavo-cylindrical lens (5) in the orthogonal plane. The laser is employed in eye-surgery in conjunction with an optical laser for examination of the retina along the same optical axis. ADVANTAGE - Resultant image is more uniform in intensity and less variable with changes in laser power.

Title: Fibre optic measurement sensor
Inventor: WEISERT HERBERT
IPC: G01G3/12
Filed: 1991-05-18
Abstract: The sensor includes an opto-mechanic converter which comprises a disc (5) with a reflection zone (12), which is tilted through a physical size to be measured, as well as a lens with a coupled optical fibre. A ray of light directed over the lens onto the reflection zone of the membrane is reflected by it into the lens, and thence into the optical fibre, from which it is taken as measurement signal. The reflection zone is composed of a tongue (7) separated from the disc. The tongue projects from the disc in such way that a tongue base (8) is located in a neutral-angle oscillation area (9) of the disc. The material of the disc, as well as the shape of the tongue, are preferably chosen in reference to its specific weight and elasticity modulus, in such a way that the resonance frequency lies in the upper end of or above a frequency range to be transferred.

Patent DE-4202681-A1 (DE)
Title: Fluid-extracting press
Inventor: AMOS GUENTER
IPC: B30B9/24
Filed: 1992-01-31
Abstract: The press extracts fluid from material, having press rollers (3-6) in line with each other and on parallel transverse axes in a frame (1), and between which guide rollers (7-9) are mounted. A driven strainer belt (11) runs in a zigzag pattern in the travel direction of the material round the successive press and guide rollers, below the former and above the latter. A loading system (13) preceding the first press roller delivers the material into the gap (12) between it and the belt, while a guide bar (14) or brush roller clear of the latter detaches the material from each press roller and delivers it onto the belt, while other guides, (15, 17, 18) direct material and belt onto the next press roller. A mechanism (21-23) following the last press roller extracts the pressed material and cleans the belt. Below the rollers is a fluid-collecting and drainage system (19, 20), while return rollers (26-29) in the frame and parallel to the press rollers guide the belt back to the first press roller.

Title: High pressure water jet equipment for cleaning out pipework etc. - has limit clutch in lance hose feed drive so that lance advances with pecking action when obstruction in pipe is encountered
Inventor: GRAHAC MIRKO DIPL ING
IPC: B08B9/053
Filed: 1992-04-03
Abstract: High pressure water is supplied through a stiff hose (5) which is fed out by rotation of the drum (4). The extending hose with a nozzle head (8) forms a lance (7) which moves in the direction (P) along the pipe. In the motor drive to the drum is a limit clutch (16). The torque limit is set above the value required to overcome the normal reaction force of the high pressure water jet as the lance advances. If however the pipe being cleaned is blocked the resistance increases until the balls (22) of the clutch ride out of depressions in plates (19) and (25) effectively disengaging the drive. The lance is now pushed back from the obstruction until the balls reseat and the clutch is once more engaged. This pecking action prevents over-feeding and maintains an optimum distance of the jet from the obstruction. USE/ADVANTAGE - More effective cleaning action and reduced cleaning time.
